  9. Customization of 2010 Census Operations • Tract Action Plan - options for each Local Census Office (LCO) to use specific to tracts with high hard-to-count scores • Specific activities within 3 main areas: • Recruiting • Partnership • Data Collection/Enumeration • “All Census is Local” 9

  12. Current Status • Finished followup on 47 million nonrespondent units, using about 600,000 interviewers • In middle of final quality assurance steps doubling checking status of complicated cases • Starting post-enumeration sample survey

  13. Head’s Up! A Confusing Few Months Ahead • September – One-year 2009 ACS estimates • December – 2010 Demographic Analysis • December – 2005-2009 five-year ACS estimates • December – 2010 decennial census state counts, reapportionment results

  14. Outline • Overview of 2010 Census Operations • Concepts of Quality in a Census • NCHS and Census 15

  15. Concepts of Quality in a Census • Distance from an Ideal Outcome • Similarity to an Alternative • Soundness of Process of Data Collection

  16. No Two Uses of Census Counts have the Same Quality These have different challenges • Total population count of the US • Total population count of each of the 50 states • Total population count of each of the 8 million census blocks • Total African-American, Hispanic, Asian population count of each of the 8 million blocks

  17. 1. Distance from an Ideal Outcome • Common evaluation with known truth • Percentage correct on examinations • Percentage unscheduled downtime for computer systems • Ideal for all population enumeration use: • “Count every resident once and only once and in the right place” • For a census we have no measured ideal

  18. 2. Similarity to an Alternative • Demographic Analysis (Fall, 2010) • Vital registration system supplies births, deaths • Emigration and immigration from records and diverse other sources • National totals for age by gender by race/ethnicity • Weaknesses • Undocumented immigration • Ethnicity measurement on records

  19. 2. Similarity to an Alternative (contd.) • Post-enumeration sample survey (2012) • Matches and nonmatches to census records • Estimates of matches and nonmatches for states and larger areas • Weaknesses • Subject to sampling variance • “correlation bias” • Recall error re April 1 status

  25. NCHS in the Statistical World • A science-driven statistical agency • For many years a key contributor to innovation in measurement, processing, and dissemination of important statistical information for the US • A voice for quality and the need for statistical independence

  26. Key Partnerships between NCHS and Census • A sister agency of the Federal statistical system • Household surveys • National Health Interview Survey • Facility surveys • The National Ambulatory Medical Care Survey • The National Hospital Ambulatory Medical Care Survey • National Hospital Discharge Survey • Data dissemination • Statistical re-use of administrative records
